Question

I need help!I have the answer but I need the work!

Answer 1

Answer:

  C is the correct answer

Step-by-step explanation:

There is no "work." The question is a reading comprehension question, so the work goes on in your brain, where the words are interpreted. The problem statement tells you ...

  "... the amount of calories he has used, f(d), is a function of the number of days, d, he has exercised with the new routine."

You are comparing this wording to the answer choice wording. The best match is to C (as you know), which says ...

  "f(15) = 5250 means after 15 days of exercising with his new routine, Vincent has used 5250 calories."

Answer 2

B can be right but if he dont do the exercises it is wrong

so it is C because d=day so it is 15 day and the results of the function is calories he used to do the exercises so the answer is C
